This species of alien is extremely strange and outlandish compared to that of earth creatures and even other aliens. They breath in the elements found in Mercury's exosphere: Sodium, Potassium, Hydrogen, Oxygen and Helium. It isn't known what happens to these chemicals inside its body but once they breathe in their bodies start to swell. Because they are so close to the sun they had to adapt to the extreme heat however it didn't adapt to freezing cold nights, because of this if they are caught in the shade for under an hour they will slowly freeze to death. They float around in the air using their tiny arms to 'swim' through it. It is unknown what they eat / drink or if they even eat / drink at all.
